In a series first, tech operator Eric Beale (Barrett Foa) goes undercover to ensure classified technology remains secure after a rocket-engine expert is killed. For Foa, that meant temporarily trading in Eric's standard surfer-dude attire — "I'd look in the mirror and say, 'Oh my God, I'm actually wearing shoes with laces and long pants. Who am I?'" — and going on location to the desert, an airport hangar, and a farm. "There's a horse that won't behave — neighing and bucking during takes, and some guy with a stick chasing chickens trying to get them in the shot. I was like, 'This is different than the computer room in the ops center.'" — Mandi Bierly
